MACHINE FOR PRESSING WADS OF WAX FOR USE iN FlRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 247,832, dated October4, 1881.

Application filed April 25, 1881.

To all whom it may concern Be it known that I, WILHELM LORENZ, engineerand manufacturer, residing and doing business in Oarlsruhe city, in theGrand Duchy of Baden, German Empire, have invented a Machine forPressing Wads of Wax for Use in Fire-Arms, of which the following is aspecification.

The accompanying drawings form a part of this specification, andrepresent what I consider the best manner of carrying out the invention.

Figure 1 is a side elevation. Fig.2 is an en View. Fig.3 is a sectioncorresponding to Fig. 1, but with the vibrating parts in their extremeleft position. Fig. 4is a plan view. Fig. 5 is a vertical section.

Similarletters ot'reference indicate like parts in all the figures.

V is the upright, which is enlarged into a supporting trains-work at thetop, where the various moving parts and stationary parts find bearingsand supports.

X is a main shaft,sustained in the boxesV'. On its end it bears theband-wheel B. By means of cams on this shaftthe entire mechanism aboutto be described is operated.

a is the press-cylinder, in which the wads of The wax is fed up in longropes through the feed-tube A, and is cut oif and placed in thepress-cylinder in the manner hereinafter to be described.

On the shaftXare the disksGH, with eccentric grooves in theircircumference. In these grooves short arms of the levers d f work. Thelever d has the short arm 6, which rocks a shaft, 0, to which isattached the knife B, for cutting off the lengths of wax as it is fed upthrough the tube A, and the knock-off arm F, which removes the wad fromthe end of the die after it has been pressed in the cylinder to. Thelever f has a short arm, 5/, which rocks a shaft, 0, to which isattached the lever O,

stamps opened. But when the cams J J overcem the action of the springthe stamps are brought together and press the wax in the cylinder a.

On top of the framing a water-pot, N, is suspended, which drips waterupon the tools to prevent the wax sticking to them.

By this machine wads are made of wax wire, (by which I mean continuouslengths of firm but sufliciently-plastie material,\vhich may be beeswaxor analogous material,) which is led to the same through the tube A in acontinuous forward movement. At an appropriate moment the knife B cutsoff a disk of a certain thickness, which is then elevated by the lever Oto the center of the axis of the top and bottom stamps. The thickness ofthe disk to be cut is regulated by a slower or faster shoving forward ofthe wax wire. The elevated wax disk is now taken up by the topstamp,D,and pushed into the press-cylinder a, to the orifice of whichthe bottom stamp, E, has moved to prevent the disk from falling down.The top and bottom stamps move now with equal speed up to the center ofthe press-cylinder, where the pressing of the wad occurs, and thesuperfluous wax is, led away by a side channel. The bottom stamp, E,moves now quickly backward, while the top stamp, D, follows slowly andknocks out the finished wad. At this moment a lever, F, moves downwardand knocks off the wad, in case the same should stick to one or theother stamp. The fallen or knocked-off wads fall through the channel b,Fig. 2, into a collecting-box, P. The cutting off of the disks is donecontemporary with the knocking off of the wads, owing to the arrangementthat the knife B and leverF are placed on the same shaft, 0, which ismoved by the eccentric disk G and the levers d and e. After-this theeccentric disk H and the levers f and 9 cause the lifting-up of thepreviously-cnt-off disk, and then the stamps D and E are put in motion,as above described, by the eccentrics J and J, acting by means of therods It and upon the levers Q and L, which swing around the points q and0'. The rollers K serve to reduce the friction, and the same, with therods i and h, are pressed continuously against the eccentrics by meansof the spring M.

The water-box N serves by drops to moisten the tools. The waste-waterflows away through the pipe 0 into the box V.

The machine is started by the loose pulley R, by means of the couplingSand the hand-lever T. The whole is placed on the pillar U,leaving fromall sides free access to the machine.

I claim as my invention- 1. In a machine for forming wads of wax, thecombination ofthepress-cylinder (o and thehorizontally-moving stamps ED, substantially as set forth.

2. The combination of the knife B and lever C with the cylinder (0 andstamps D E, substantially as set forth.

3. In a wax-wad-forming machine, the combination of the cams J J, arms2' h, pivoted levers L Q, and stamps E D, substantially as set forth.

4. The combination of the cams J J, armsi h, pivoted leversLQ,spring-rod M, and stamps E D, substantially as set forth.

5. The combination of thecam-grooved disks G H, connecting-levers, androcking centers, with the knife B, knock-off lever F, and lei-er G,substantially as set forth.

In testimony whereof I have hereunto set my hand at Berlin, Prussia,this 1st day of February,1881,in the presence of two subscribingwitnesses.
